I think I am as close to cured as Is possible. By that I mean that back in 1985 I was one of my specialists sickest patients with ME/CFS/FM and I got better in about 6 weeks. Some 5 years later he was really impressed that I hadn't relapsed. I did have one relapse in 2003 after I got shingles and started the downward spiral again for 6 months till I took charge of my life again properly. Now I don't think of myself as having CFS or the others but still have to look after myself or I tend to get symptoms if I don't.
I also had two children who had it back in the 1980s. I have just seen my daughter, now 37, happy, healthy and fit. Last year she worked at a high powered job, studied part time at university, built her dream house and did 5 hours of ballet lessons a week. My son is also healthy.
So yes healing is possible.
Oh, yes, I also put together a program which had an 80% success rate at getting people with CFS symptoms into remission. it wasn't instant, but it seemed to work quite well though the doctors weren't interested as it wasn't a pill or CBT.
